Answer: ABCExplanation:https://www.safaribooksonline.com/library/view/foundation-learning-guide/9780132652933/ch06.html“Benefits of a unified fabric include the following:• Reduced cabling: Multiple Fibre Channel and Ethernet connections can be replaced with a single 10 Gigabit Ethernet connection or a dual 10 Gigabit Ethernet connection for redundancy. In many cases, access layer cabling can be reduced by 50 percent, or even more if the server uses multiple 1 Gigabit Ethernet connections.• Fewer access layer switches: In a typical top-of-rack (TOR) design, shown at the top of Figure 6-20, each rack contains at least four separate switches: two Ethernet switches to support redundant LAN connections and two Fibre Channel switches to support redundant SAN connections. By consolidating LAN and SAN connectivity on a single network, as shown in the lower part of Figure 6-20, each rack needs just two access switches that can provide both redundant LAN and SAN connectivity. • Fewer network adapters per server: By combining LAN and SAN connectivity on a single 10 Gigabit Ethernet adapter, the number of network adapters that need to be installed in each server is heavily reduced. A single converged network adapter (CNA) can replace the combination of a Fibre Channel HBA and one or more Gigabit Ethernet adapters. • Power and cooling savings: Reducing the number of access switches per rack and the number of network adapters per server leads to a reduced demand for power. The less power that is used, the less heat that is generated. This also leads to a reduction in cooling requirements. The lower number of access layer cables can also improve airflow in the data center, which can lead to more efficient use of the available cooling. • Management integration: Combining LAN, SAN, and interprocess communication (IPC) networks on a single network infrastructure not only reduces the number of managed devices but also the overall management complexity.• Wire once: Using a single type of connection, such as 10 Gigabit Ethernet, for LAN, SAN, and IPC eliminates the need to recable racks to provision storage or network connectivity to a server.
